The ultra-sensitivity of the tea crop and its yield towards the climatic factors such as the increase in temperature, soil moisture deficit and saturation vapour pressure deficit in the low elevations are well proven over the past century. Hence the tea industry in Sri Lanka is clearly vulnerable to predicted climate changes, and greater economic, social and environmental problems. This research hence studies the effect of weather patterns and terrain factors on tea productivity. It also covers the effect of climate change on crop production.
This research project has been instrumental in implementing a key objective of the research centre- to be a platform where young scientists and researchers can engage and undertake climate related research. It will also act as a resource hub and educational facility. At present a young undergraduate student Ms. Dharshani Perera from the University of Colombo, Sri Lanka is conducting field work here.
An ongoing database of climate data has been initiated, which will expand into a nationwide climate monitoring system.
